I've been using the STL a little recently and can't really call
myself an expert - but I've found that always typing in the
container's name up to three times for a find or twice for other
actions is getting a little error-prone, for example:

	// check if already there
	vector<int> myVector; // this is a _short_ name
	if (find(myVector.begin(), myVector.end(), someInt)
		 == myVector.end())
	{
	  // not there
	}

I find this more than a little error-prone, why isn't there
something like:

	template <class Container, class Item>
	bool find(Container &c, Item const &v, Container::iterator &i)
	{
	    i = find(c.begin(), c.end(), v);
	    return i != c.end();
	}

So the above becomes:
	Container::iterator i;
	if (!find(myVector, someInt, i)) 
	{
	  // not there
	}

One argument against this is 'the programmer can write their own' -
but this is true for most things - the libraries are there to
provide a useful (and hopefully less error-prone) implementation so
the programmer doesn't have to write their own.
